PDB Ligand
Compound class: Synthetic organic
Comment: Izorlisib (MEN1611 and formerly CH5132799) is described as a potent, orally available class I PI3K inhibitor [1]. Clinical development of CH5132799 has been licenced to Menarini Pharma from Chugai Pharmaceutical Co, hence the change in research code.
The chemical structure of MEN1611 is identical to that which was submitted to the WHO for the INN izorlisib (proposed INN list 126, Jan 2022).
